For a square footing, determine the gross allowable load, Qall, that the footing can carry. Use Terzaghi,s equation for general shear failure ( fs=3.5). Given : Density of soil above the underground table, p=1800 kg/m^3, saturated soil density below the underground table, P sat=1980 kg/m^3, c=24 kN/m^2, $=25°, B=1.8 m, Df=1.2 m and h=2 m.
A square footing is subjected to an inclined load as shown in the figure below. If the size of the footing ,B=2.25 m , determine the gross allowable inclined load , Q, that the footing can carry. Given: = 120 andF.S = 3.5.
Using Meyerhof's General Bearing Capacity Equation, calculate the Net Allowable Bearing Capacity of the footing shown with the following data:
For SOIL,
Cohesion, c = 19 kPa
The angle of internal friction =23
Unit weight of moist soil, y = 19 kN/m3
Unit weight of submerged soil, ysub= 11 kN/m3
For footing,
X=4.2m
Y=3.5m
Df=3.2m
Use a Factor of Safety of 3
The load is inclined at an angle with the vertical Beta, B = 33 degrees
Note:
As much as possible round off only on the final answer.
